YARN supports the notion of **resource reservation** via the [ReservationSystem](./ReservationSystem.html), a component that allows users to specify a profile of resources over-time and temporal constraints (e.g., deadlines), and reserve resources to ensure the predictable execution of important jobs.The *ReservationSystem* tracks resources over-time, performs admission control for reservations, and dynamically instruct the underlying scheduler to ensure that the reservation is fullfilled.

In order to scale YARN beyond few thousands nodes, YARN supports the notion of **Federation** via the [YARN Federation](.Federation.html) feature. Federation allows to transparently wire together multiple yarn (sub-)clusters, and
make them appear as a single massive cluster. This can be used to achieve larger scale, and/or to allow multiple independent clusters to be used together for very large jobs, or for tenants who have capacity across all of them.
